This calculator will give you a pretty good idea of what your payments might be on any given house. Of course our disclaimer is that all figures need to be confirmed. Taxes, home owner insurance, mortgage insurance etc. But, as I said, it should give you a very reasonable estimate, and hopefully that is helpful.
This mortgage calculator can be used to figure out monthly payments of a home mortgage loan, based on the home's sale price, the term of the loan desired, buyer's down payment percentage, and the loan's interest rate. This calculator factors in PMI (Private Mortgage Insurance) for loans where less than 20% is put as a down payment. Also taken into consideration are the town property taxes, and their effect on the total monthly mortgage payment.
